ILLINOIS Application led May 3,

Our invention relates to improvements in filling mechanisms, and it consists in the combinations, constructions, and arrangements herein described and claimed.

In machines which fillV bottles, that have a certain amount of air pressure therein, with liquid, the air pressure increases with an equal rapidity to the increase of the liquid within the bottles.

An object of our invention is to provide means for releasing a desired Vamount of air pressure from a bottle at a predetermined point. Y,

A further object of our invention is to provide a device of the type described which will shut off the air pressure supply into the bottles, close the liquid control-valve, and free the bottles so as to permit a desired amount of air pressure to escape at a predetermined oint.

Other o jects and advantages will appear in the following specification, and the novel features of the invention will be particularly pointed out in the appended claims.

Our invention is illustrated in the accompanying drawings, forming part of this ap-` plication, in which Figure 1 is a sectional view of the device, parts thereof being shown in elevation,

Figure 2 is enlarged portions of the de.- vice, and

Figure 3 is a side elevation of a portion of the device.

In carrying outour invention, we pror vide a liquidtank 1 having a plurality of liquid control units 2 disposed therein.4 An air pressure supply pipe 3 is connected to each unit. A spring-pressed valve 4 which is disposed within each filling unit 2 tendsv to close the passageway which is in communication with the air pressure supply 3. TheI valve 4 is provided with an integral tube 6 which extends downwardly therefrom to a point beyond the lower extremity of the filling unit 2. VA filling tube 7 passes throughA the valve 4, the tube 6, and extends downwardly, having at its lower end a liquid control valve, not shown. A bottle-centering4 bell 8 is disposed concentric with the illing FILLING ILIECIIANISIII` 192e. i serial No. 106,493.

tube 7 and is ada ted to engage with the lower end of the tu e 6.

The bottle-raising means consists of arms 9 pivotally mounted at 'one end to apmovable support 10, and at'the other end to connecting rods 11. The connecting rods 11 are operatively connected to cylinders 12 which are slidably disposed Within bearings 13. The bearings 13 are mounted in a movable Vsupport 13. Bottle supports 14 are disposedl on the upper ends of the cylinders 12 and are adapted to receive bottles 15. A

co l

saucer-'shaped vsupport 16 is rigidly mountf ed upon a stationary support 17 and is provided with a tapering surface-18. The support 16 is cutk away at 19'so as to receive cam lates 2O of the shape shown in Figure 2. he cam plates 20 can be secured to the support 16 in any desired manner'. The ends 21 of the cam plates are tapered for a pur-L pose hereinafter described. rThe arms 9 are y provided with cam rollers 22 whicharey "adapted to contact with the surface 18 of 25 is rigidly secured at its lower end to the stationary support '17, andis provided'with a knock-out stand 26 disposed upon the upper endthereof. Thestand 26 is provided 'with downwardly extending ends 27 and y27 which are adapted to engagewith pins 28 on the projections 24.`

From the foregoing description of the various parts vof the device, the operation thereof may be readily understood. The bottles 15 are placed upon the supports 14 as theirV corresponding rollers 22 ride downwardly upon acam strip 29 of the support .16. As the rollers 22 ride upwardly to and .upon the surfacelS of the support 16, the

bottles are also raised upwardly. During the holding each of the bottles upward movement of each bottle, the bottlecentering bell 8 strikes against the lower end of the tube 6 and raises the valve l upwardly, thus permitting the air pressure to pass into the bottle. In this manner, liquid 30 is permitted to flow into the bottle under air pressure. As the liquid passes into thel bottle, the air pressure therein gradiutlly increases. The air pressure supply accumulates so as to temporarily retard the flow of liquid intoY the bottle, the result being that the bottle is not filled :tast enough. To overcome this, and at the same time to release any unbalanced pressure in the bottle so as to lill the bottle to the same level and prevent any foaming when the bottle is released, it is necessary to release a part ot' the counter-pressure in the bottle. To accomplish this, the pins 2S engage with the downwardly extending end 27 and ride upon the upper suriace ot the knock-out stand 2G. Atlthe san e time, the corresponding roller 22 passes up the inclined end of the cam plate 20. In this manner, the arm 9 is raised a sutlicient c istance to permit the latch 23 together with the latch seat 23' to swing outwardly about its pivot. `he roller 22 is now free to ride downwardly on the cam plate 20. In this manner, the bottle is lowered a. suflicient distance to close the valve 4, thus cutting oil' the air pressure supply into the bottle, and permitting a small amount of the air pressure to escape from the bottle. lVhen this is completed, the roller 22 rides upwardly a sufficient distance to permit the latch to again swing beneath the arm 9 as the pin 28 thereon rides downwardly upon the end 27 and disengages therewith. The bottle is again held in filling position, and the bottle permitted to be iilled to a desired height.

It is obvious that as many cam plates 20 can be placed upon the support lG as desired. A knockout stand 2o is provided tor each cam plate 20 and the cam strip 29. rlhe latches 23 are moved away .troni the arms 9 after the arms have been raised due to their rollers engaging with the cam strip or cam plates, and are held away until the arms are again raised by the cam strip or cam plates.
